Abstract
OBJECTIVES To derive systematic review informed, modified Delphi consensus regarding monitoring and replacement of specific coagulation factors during pediatric extracorporeal membrane oxygenation (ECMO) support for the Pediatric ECMO Anticoagulation CollaborativE. DATA SOURCES A structured literature search was performed using PubMed, Embase, and Cochrane Library (CENTRAL) databases from January 1988 to May 2020, with an update in May 2021. STUDY SELECTION Included studies assessed monitoring and replacement of antithrombin, fibrinogen, and von Willebrand factor in pediatric ECMO support. DATA EXTRACTION Two authors reviewed all citations independently, with conflicts resolved by a third reviewer if required. Twenty-nine references were used for data extraction and informed recommendations. Evidence tables were constructed using a standardized data extraction form. DATA SYNTHESIS Risk of bias was assessed using the Quality in Prognosis Studies tool. The evidence was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation system. A panel of 48 experts met over 2 years to develop evidence-based recommendations and, when evidence was lacking, expert-based consensus statements. A web-based modified Delphi process was used to build consensus via the Research And Development/University of California Appropriateness Method. Consensus was defined as greater than 80% agreement. We developed one weak recommendation and four expert consensus statements. CONCLUSIONS There is insufficient evidence to formulate recommendations on monitoring and replacement of antithrombin, fibrinogen, and von Willebrand factor in pediatric patients on ECMO. Optimal monitoring and parameters for replacement of key hemostasis parameters is largely unknown.

Abstract
OBJECTIVES To identify and prioritize research questions for anticoagulation and hemostasis management of neonates and children supported with extracorporeal membrane oxygenation (ECMO) from the Pediatric ECMO Anticoagulation CollaborativE (PEACE) consensus. DATA SOURCES Systematic review was performed using PubMed, EMBASE, and Cochrane Library (CENTRAL) databases from January 1988 to May 2021, followed by serial consensus conferences of international, interprofessional experts in the management of ECMO for critically ill neonates and children. STUDY SELECTION The management of ECMO anticoagulation for critically ill neonates and children. DATA EXTRACTION Within each of the eight subgroups, two authors reviewed all citations independently, with a third independent reviewer resolving any conflicts. DATA SYNTHESIS Following the systematic review of MEDLINE, EMBASE, and Cochrane Library databases from January 1988 to May 2021, and the consensus process for clinical recommendations and consensus statements, PEACE panel experts constructed research priorities using the Child Health and Nutrition Research Initiative methodology. Twenty research topics were prioritized, falling within five domains (definitions and outcomes, therapeutics, anticoagulant monitoring, protocolized management, and impact of the ECMO circuit and its components on hemostasis). CONCLUSIONS We present the research priorities identified by the PEACE expert panel after a systematic review of existing evidence informing clinical care of neonates and children managed with ECMO. More research is required within the five identified domains to ultimately inform and improve the care of this vulnerable population.

Abstract
OBJECTIVES To derive systematic-review informed, modified Delphi consensus regarding anticoagulation monitoring assays and target levels in pediatric extracorporeal membrane oxygenation (ECMO) for the Pediatric ECMO Anticoagulation CollaborativE. DATA SOURCES A structured literature search was performed using PubMed, EMBASE, and Cochrane Library (CENTRAL) databases from January 1988 to May 2021. STUDY SELECTION Anticoagulation monitoring of pediatric patients on ECMO. DATA EXTRACTION Two authors reviewed all citations independently, with a third independent reviewer resolving any conflicts. Evidence tables were constructed using a standardized data extraction form. DATA SYNTHESIS Risk of bias was assessed using the Quality in Prognosis Studies tool or the revised Cochrane risk of bias for randomized trials, as appropriate and the evidence was evaluated using the Grading of Recommendations Assessment, Development and Evaluation system. Forty-eight experts met over 2 years to develop evidence-based recommendations and, when evidence was lacking, expert-based consensus statements for clinical recommendations focused on anticoagulation monitoring and targets, using a web-based modified Delphi process to build consensus (defined as > 80% agreement). One weak recommendation, two consensus statements, and three good practice statements were developed and, in all, agreement greater than 80% was reached. We also derived some resources for anticoagulation monitoring for ECMO clinician use at the bedside. CONCLUSIONS There is insufficient evidence to formulate optimal anticoagulation monitoring during pediatric ECMO, but we propose one recommendation, two consensus and three good practice statements. Overall, the available pediatric evidence is poor and significant gaps exist in the literature.

Patient-tailored platelet transfusion practices for children supported by extracorporeal membrane oxygenation. Vox Sang 2024; 119:326-334. [PMID: 38175143 DOI: 10.1111/vox.13583] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2023] [Revised: 12/01/2023] [Accepted: 12/08/2023] [Indexed: 01/05/2024]
Abstract
BACKGROUND AND OBJECTIVES Extracorporeal membrane oxygenation (ECMO) serves as cardiopulmonary therapy in critically ill patients with respiratory/heart failure and often necessitates multiple blood product transfusions. The administration of platelet transfusions during ECMO is triggered by the presence or risk of significant bleeding. Most paediatric ECMO programmes follow guidelines that recommend a platelet transfusion threshold of 80-100 × 109/L. To reduce exposure to platelets, we developed a practice to dynamically lower the threshold to ~20 × 109/L. We describe our experience with patient-tailored platelet thresholds and related bleeding outcomes. MATERIALS AND METHODS We retrospectively evaluated our platelet transfusion policy, bleeding complications and patient outcome in 229 ECMO-supported paediatric patients in our unit. RESULTS We found that more than 97.4% of patients had a platelet count <100 × 109/L at some point during their ECMO course. Platelets were transfused only on 28.5% of ECMO days; and 19.2% of patients never required a platelet transfusion. The median lowest platelet count in children who had bleeding events was 25 × 109/L as compared to 33 × 109/L in children who did not bleed (p < 0.001). Our patients received fewer platelet transfusions and did not require more red blood cell transfusions, nor did they experience more haemorrhagic complications. CONCLUSION We have shown that a restrictive, 'patient-tailored' rather than 'goal-directed' platelet transfusion policy is feasible and safe, which can greatly reduce the use of platelet products. Although there was a difference in the lowest platelet counts in children who bled versus those who did not, the median counts were much lower than current recommendations.

Abstract
Unfractionated heparin (UFH) is the most used anticoagulant in patients receiving veno-venous extracorporeal membrane oxygenation (VV-ECMO). Its therapeutic levels are monitored using activated partial thromboplastin time ratio (aPTTr) or antifactor Xa (anti-Xa) assay. This was a retrospective, single-center, cohort study where all adult patients with viral etiology respiratory failure requiring VV-ECMO from January 2, 2015 to January 31, 2022 were included. Anticoagulation was monitored using aPTTr (until November 1, 2019) or anti-Xa assay (after November 1, 2019). We compared the accuracy and precision of anticoagulation monitoring tests using time in therapeutic range (TTR) and variance growth rate (VGR), respectively, and their impact on bleeding and thrombotic events (BTEs). A total of 254 patients, 74 in aPTTr and 180 in anti-Xa monitoring groups, were included with a total of 4,992 ECMO-person days. Accuracy was comparable: mean TTR of 47% in aPTTr and 51% in anti-Xa groups ( p = 0.28). Antifactor Xa monitoring group demonstrated improved precision with a lower variance (median VGR 0.21 vs. 1.61 in aPTTr, p < 0.05). Secondary outcome of less heparin prescription changes (adjusted rate ratio [RR] = 1.01, p = 0.01), fewer blood transfusions (adjusted RR = 0.78, p < 0.05), and ECMO circuit changes (adjusted RR = 0.68, p < 0.05) were seen with anti-Xa monitoring.

Abstract
The assessment of hemostatic disorders in neonates is crucial, but remains challenging for clinicians. Although the concept of developmental hemostasis is widely accepted among hemostasis specialists globally, it is probably under-recognized by clinicians and laboratory practitioners. In parallel with age-dependent hemostatic status maturation, comprehension of the differences between normal values is crucial for the accurate diagnosis of potential hemorrhagic and thrombotic disorders of the vulnerable neonatal population. This review outlines the basics of developmental hemostasis and the features of the available coagulation testing methods, with a focus on novel tools for evaluating the neonatal hemostatic profile. Common errors, issues, and pitfalls during the assessment of neonatal hemostasis are discussed, along with their impact on patient management. Current knowledge gaps and research areas are addressed. Further studying to improve our understanding of developmental hemostasis and its reflection on everyday clinical practice is warranted.

Abstract
The term heparin resistance (HR) is used by clinicians without specific criteria. We performed a literature search and surveyed our SSC membership to better define the term when applied to medical and intensive care unit patients. The most common heparin dosing strategy reported in the literature (53%) and by survey respondents (80.4%) was the use of weight-based dosing. Heparin monitoring results were similar based on the proportion of publications and respondents that reported the use of anti-Xa and activated partial thromboplastin time. The most common literature definition of HR was >35 000 U/d, but no consensus was reported among survey respondents regarding weight-based and the total dose of heparin when determining resistance. Respondent consensus on treating HR included antithrombin supplementation, direct thrombin inhibitors, or administering more heparin as the strategies available for treating HR. A range of definitions for HR exist. Given the common use of heparin weight-based dosing, future publications employing the term HR should include weight-based definitions, monitoring assay, and target level used. Further work is needed to develop a consensus for defining HR.

Abstract
OBJECTIVES The optimal method for monitoring of anticoagulation in patients on extracorporeal life support (ECLS) is unknown. The objective of this study was to assess the relationship between anti-factor Xa level (anti-Xa; IU/mL) and activated partial thromboplastin time (aPTT; seconds) for monitoring intravenous unfractionated heparin anticoagulation in adult ECLS patients. METHODS Charts of all adult patients cannulated for ECLS from 2015 through 2017 were reviewed and laboratory and heparin infusion data were extracted for analysis. Time matched pairs of anti-Xa and aPTT were considered concordant if both laboratory values were within the same clinically utilized range. A hierarchical logistic regression model was used to determine factors associated with discordance while accounting for patient level effects. RESULTS A total of 1016 paired anti-Xa and aPTT values from 65 patients were evaluated. 500 (49.2%) paired samples were discordant with a degree of variability on linear regression (r2 = 0.315). The aPTT fell into a higher therapeutic range compared to the anti-Xa in 31.6% and lower in 17.3%. Logistic regression demonstrated that discordance was independently associated with time from initiation of ECLS (OR 1.17 per day, p < 0.001), average heparin infusion rate (OR 1.25 per U/kg/hr, p < 0.001), and INR (OR 3.22, p < 0.001). CONCLUSIONS Nearly half of all aPTT and anti-Xa values were in discordant ranges and discordance is more likely as the time on ECLS and the INR level increase. The use of either assay in isolation to guide heparin anticoagulation may lead to misestimation of the degree of anticoagulation in complex ECLS patients.

Abstract
INTRODUCTION Extracorporeal membrane oxygenation (ECMO) circuits may be changed during the run for multiple reasons; however, these circuit changes may be associated with adverse events. Predictors for undergoing a circuit change (CC) and their outcomes remain unclear. We hypothesized that neonatal and pediatric CC correlates with increased morbidity and mortality. METHODS Pediatric and neonatal patients who underwent one ECMO run lasting <30 days at a tertiary children's hospital from 2011 through 2017 were retrospectively reviewed. Bivariate regression analysis evaluated factors associated with ECMO mortality and morbidity. LASSO logistic regression models identified independent risk factors for undergoing a CC. p < .05 was significant. RESULTS One hundred 85 patients were included; 137 (74%) underwent no CC, while 48 (26%) underwent one or more. Undergoing a CC was associated with longer ECMO duration (p < .001), higher blood transfusion volumes (p < .001), increased hemorrhagic complications (p < .001) and increased mortality (p = .002). Increased platelet (p = .001) and FFP (p = .016) transfusion volumes at any time while on ECMO were independent factors associated with undergoing a CC. CONCLUSIONS Changing the circuit during the ECMO run occurs frequently and may be associated with poorer outcomes. Understanding the outcomes and predictors for CC may guide management protocols for more efficient circuit changes given its important association with overall outcomes.

Abstract
INTRODUCTION To determine if anti-Xa testing is associated with improved outcomes for patients <19-years-old on ECMO. METHODS We evaluated the clinical benefit of anti-Xa heparin monitoring utilizing the Bleeding and Thrombosis during ECMO (BATE) database of 514 patients <19-years-old. The BATE database includes incidences of bleeding, thrombosis, and mortality. The database also describes anti-coagulation test utilization. We grouped and analyzed patients based on ECMO indication (cardiac, respiratory, or extracorporeal cardiopulmonary resuscitation [E-CPR]) and age (neonatal vs pediatric). We constructed multivariable logistic regression models to analyze the impact of anti-Xa testing on mortality, bleeding, and thrombosis in each group. RESULTS Across the entire population, anti-Xa testing did not have a significant effect on the incidence of mortality (43% with anti-Xa testing vs 49% without), bleeding (68% vs 74%), or thrombosis (37% vs 39%). However, among cardiac indicated patients on ECMO (n = 207), anti-Xa testing was significantly associated with reduced odds ratio (OR) of mortality (adjusted OR 0.527, p = .040) and bleeding (adjusted OR 0.369, p = .021). In addition, among neonatal patients on ECMO (n = 264), anti-Xa testing was associated with a significant reduction in the odds ratio of bleeding (adjusted OR 0.534, p = .046). CONCLUSION Anti-Xa testing is associated with improved outcomes among cardiac indicated and neonatal patients on ECMO. Additional research to find the optimal heparin monitoring regimen is needed to better support these critically ill patients. In the interim, we recommend clinicians consider utilizing anti-Xa assays as part of their heparin monitoring plan for neonatal and cardiac indicated patients on ECMO.

Abstract
Assessing coagulation status is essential for prompt intervention to reduce morbidity and mortality related to bleeding and thrombotic complications during the perioperative period. Traditional coagulation tests such as platelet count, activated partial thromboplastin time (aPTT), prothrombin time (PT), international normalized ratio (INR), and activated clotting time (ACT) provide only static evaluation. These tests are not designed for assessment of dynamically changing coagulation conditions during the perioperative time. However, viscoelastic coagulation testing such as thromboelastography (TEG) produces a rapid numerical and graphical representation that helps to detect and direct targeted hemostatic therapy. Searching the literature through PubMed, Medline, Ovid, CINAHL, and ClinicalTrials.gov we retrieved 210 studies, which represent the use of TEG in the perioperative period. The included studies were categorized under various settings such as trauma, obstetrics, orthopedics, intensive care unit (ICU), cardiovascular, transplant, and miscellaneous scenarios. TEG showed promising results in trauma surgeries in predicting mortality, hypercoagulability, and bleeding even when it was compared to conventional methods. TEG was also useful in monitoring anticoagulant therapy in orthopedic and obstetric surgeries; however, its role in predicting thrombotic events, hypercoagulability, or complications was questionable. In ICU patients, it showed promising results, especially in the prediction or improvement of sepsis, coagulopathy, thrombotic events, ICU duration, hospital stay, and ventilator duration. TEG parameters effectively predicted hypercoagulation in transplant surgeries. Regarding cardiovascular surgeries, they were effective in the prediction of the need for blood products, coagulopathy, thrombotic events, and monitoring anticoagulation therapy. More randomized clinical trials comparing TEG parameters with standardized tools are needed to produce robust results to standardize its use in different perioperative settings.

Abstract
AIMS There remains a paucity of literature regarding best practice for antithrombin (AT) monitoring, dosing and dose-response in paediatric extracorporeal membrane oxygenation (ECMO) patients. METHODS We conducted a retrospective cohort study at a quaternary care paediatric intensive care unit in all patients <18 years of age supported on ECMO from 1 June 2011 to 30 April 2020. Adverse events and outcomes were characterized for all ECMO runs. AT activity and replacement were characterized and compared between two clinical protocols. AT activities measured post- vs. pre-AT replacement were compared in order to characterize a dose-response relationship. RESULTS The final cohort included 191 patients with 201 ECMO runs and 2028 AT activity measurements. The median AT activity was 65% (interquartile range [IQR], 51-82) and 879 (43.3%) measurements met the criteria of deficient. The overall median AT dose and increase in AT activity were 50.6 units/kg/dose (IQR, 39.5-67.2) and 23.5% (IQR, 9.8-36.0), respectively. In the protocol that restricted AT activity measurements to clinical scenarios concerning for heparin resistance, there was significantly higher dosing in conjunction with significantly fewer overall administrations. Approximately one third of AT activity remained deficient after repletion. There was no difference in mechanical complications, reasons for discontinuation of ECMO support, time on ECMO or survival between protocols. CONCLUSIONS There was a high prevalence of AT deficiency in paediatric ECMO patients. An AT replacement protocol based on evaluating heparin resistance is associated with fewer AT administrations, with similar circuit and patient outcomes. Further data are needed to identify optimal dosing strategies.

Abstract
Anticoagulation of patients supported by extracorporeal membrane oxygenation is challenging because of a high risk of both bleeding and thrombotic complications, and often empirical. Practice in anticoagulation management is therefore highly variable. The scope of this guidance document is to provide clinicians with practical advice on the choice of an anticoagulant agent, dosing, and the optimal anticoagulant monitoring strategy during extracorporeal membrane oxygenation support in adult patients.

Abstract
Extracorporeal membrane oxygenation (ECMO) can provide life-saving support for critically ill patients suffering severe respiratory and/or cardiac failure. However, thrombosis and bleeding remain common and complex problems to manage. Key causes of thrombosis in ECMO patients include blood contact to pro-thrombotic and non-physiological surfaces, as well as high shearing forces in the pump and membrane oxygenator. On the other hand, adverse effects of anticoagulant, thrombocytopenia, platelet dysfunction, acquired von Willebrand syndrome, and hyperfibrinolysis are all established as causes of bleeding. Finding safe and effective anticoagulants that balance thrombosis and bleeding risk remains challenging. This review highlights commonly used anticoagulants in ECMO, including their mechanism of action, monitoring methods, strengths and limitations. It further elaborates on existing anticoagulant monitoring strategies, indicating their target range, benefits and drawbacks. Finally, it introduces several highly novel approaches to real-time anticoagulation monitoring methods including sound, optical, fluorescent, and electrical measurement as well as their working principles and future directions for research.

Abstract
OBJECTIVE To evaluate an institutional practice change from an extracorporeal life support (ECLS) anticoagulation monitoring strategy of activated clotting time (ACT) alone to a multimodal strategy including ACT, activated partial thrombin time, heparin anti-factor-Xa, and thromboelastography. METHODS This was a retrospective review of patients younger than 18 years on ECLS and heparin between January 2014 and June 2020 at a single institution. RESULTS Twenty-seven patients used an ACT-directed strategy and 25 used a multimodal strategy. The ACT-directed group was on ECLS for a shorter median duration than the multimodal group (136 versus 164 hours; p = 0.046). There was a non-significant increase in major hemorrhage (85.1% versus 60%; p = 0.061) and a significantly higher incidence of central nervous system (CNS) hemorrhage in the ACT-directed group (29.6% versus 0%; p = 0.004). Rates of thrombosis were similar, with a median of 3 circuit changes per group (p = 0.921). The ACT-directed group had larger median heparin doses (55 versus 34 units/kg/hr; p < 0.001), required more dose adjustments per day (3.8 versus 1.7; p < 0.001), and had higher rates of heparin doses >50 units/kg/hr (62.9% versus 16%; p = 0.001). More anticoagulation parameters were supratherapeutic (p = 0.015) and fewer were therapeutic (p < 0.001) in the ACT-directed group. CONCLUSIONS Patients with a multimodal strategy for monitoring anticoagulation during ECLS had lower rates of CNS hemorrhage and decreased need for large heparin doses of >50 units/kg/hr without an increase in clotting complications, compared with ACT-directed anticoagulation. Multimodal anticoagulation monitoring appears superior to ACT-only strategies and may reduce heparin exposure and risk of hemorrhagic complications for pediatric patients on ECLS.

Abstract
Bleeding and thrombosis frequently occur in pediatric patients with extracorporeal membrane oxygenation (ECMO) therapy. Until now, most patients are anticoagulated with unfractionated heparin (UFH). However, heparin has many disadvantages, such as binding to other plasma proteins and endothelial cells in addition to antithrombin, causing an unpredictable response, challenging monitoring, development of heparin resistance, and risk of heparin-induced thrombocytopenia (HIT). Direct thrombin inhibitors (DTIs), such as bivalirudin and argatroban, might be a good alternative. This review will discuss the use of both UFH and DTIs in pediatric patients with ECMO therapy.

Abstract
Anticoagulation management in pediatric extracorporeal membrane oxygenation (ECMO) is challenging with multiple laboratory measures utilized across institutions without consensus guidelines. These include partial thromboplastin time (PTT), thromboelastography (TEG), and antifactor Xa (aXa). We aimed to evaluate the consistency of TEG R-time, PTT, and aXa correlation to bivalirudin and heparin dosing. We conducted a single-center restrospective review of pediatric ECMO cases from 2018 to 2020 anticoagulated with bivalirudin or heparin. We collected up to 14 serial simultaneous TEG R-time, PTT, and aXa measurements over a 7 day ECMO course with corresponding bivalirudin or heparin dosing. We analyzed the correlation between bivalirudin, heparin, and the three measurements of anticoagulation. A total of 67 ECMO runs, 32 bivalirudin, and 35 heparin, and more than 1,500 laboratory values, of which >80% simultaneous, were analyzed. When assessing correlations at the individual patient level, there was no consistent correlation between dosing and at least one laboratory parameter in the majority of patients. Furthermore, 44% of the bivalirudin cohort and 37% of the heparin cohort exhibited no correlation with any parameters. There were statistically significant correlations only between bivalirudin and heparin dosing and the sum total of the different laboratory tests. These inconsistencies highlight the importance of multimodality testing of anticoagulation in the management of pediatric ECMO anticoagulation and cannot be relied on in isolation from bedside clinical judgment.

Abstract
Extracorporeal membrane oxygenation (ECMO) and ventricular assist devices (VADs) are increasingly used in critically ill children. Despite improvements in mechanical design and clinical management, thromboembolic and hemorrhagic events remain significant causes of morbidity and mortality related to the use of both devices. Choice of anticoagulant agents and assays for monitoring continue to present challenges in management. In this review, we describe the incidence and risk factors for thrombosis and hemorrhage, the different types of anticoagulants currently in use, the assays available for monitoring anticoagulation, and management of thromboembolic and bleeding complications in children on mechanical circulatory support (MCS). We conclude by emphasizing the areas that need further study to minimize the risk for thrombosis and hemorrhage in the use of ECMO and VAD in children.

Abstract
Pediatric mechanical circulatory support can be lifesaving. However, managing anticoagulation is one of the most challenging aspects of care in patients requiring mechanical circulatory support. Effective anticoagulation is even more difficult in pediatric patients due to the smaller size of their blood vessels, increased turbulent flow, and developmental hemostasis. Recently, viscoelastic testing (VET) has been used as a qualitative measure of anticoagulation efficacy in patients receiving extracorporeal membrane oxygenation (ECMO) and ventricular assist devices (VAD). Thromboelastography (TEG®) and thromboelastometry (ROTEM®) provide a global qualitative assessment of hemostatic function from initiation of clot formation with the platelet-fibrin interaction, platelet aggregation, clot strength, and clot lysis. This review focuses on the TEG®/ROTEM® and important laboratory and patient considerations for interpretation in the ECMO and VAD population. We summarize the adult and pediatric ECMO/VAD literature regarding VET values, VET-platelet mapping, utility over standard laboratory monitoring, and association with outcome measures such as blood product utilization, bleeding, and thrombosis.

Abstract
Use of extracorporeal membrane oxygenation (ECMO) is increasing among critically ill adults with cardiac and/or respiratory failure. Use of ECMO is associated with hemostatic alterations requiring use of anticoagulation and blood product support. There are limited guidelines to direct transfusion management in the adult patient supported with ECMO. The objective of this article is to describe (1) the role of the transfusion service in providing transfusion support and current understanding of transfusion thresholds, (2) the complexities of monitoring anticoagulation, and (3) the consideration regarding additional factor concentrates and antifibrinolytics within the context of ECMO support. The information provided should assist ECMO care teams in informing transfusion and anticoagulation practice while highlighting key areas for future research and collaboration.

Abstract
Extracorporeal membrane oxygenation (ECMO) in pediatrics has rapidly progressed in recent years; however, there continues to be considerable variation in anticoagulation practices. In 2016, we implemented a standardized anticoagulation protocol in effort to reduce clotting and bleeding complications. A single-center retrospective analysis of pediatric patients requiring ECMO between 2014 and 2018 was performed. One hundred one ECMO cases in 94 pediatric patients met eligibility criteria (preprotocol = 64 cases; postprotocol = 37 cases). Demographics, ECMO parameters, complications, laboratories, and blood product requirements were analyzed for differences between the two groups. There was a significant decrease in the incidence of hematologic (p < 0.022), neurologic (p < 0.001), and renal complications (p < 0.001) in the postprotocol era. Incidence of bleeding, cardiac/pulmonary complications, and circuit changes were similar between the groups. The postprotocol group required fewer transfusions of red blood cells and cryoprecipitate. Additionally, platelet counts and fibrinogen levels were maintained higher in the postprotocol era. In conclusion, implementation of a standardized anticoagulation protocol was associated with improved anticoagulation parameters and a decrease in hematologic and neurologic complications, coagulopathy, renal injury, and blood product administration. We attribute these findings to transitioning to anti-Xa as a measure of heparinization and maintaining higher platelet counts.

Abstract
OBJECTIVES To present the recommendations and consensus statements with supporting literature for plasma and platelet transfusions in critically ill neonates and children undergoing cardiac surgery with cardiopulmonary bypass or supported by extracorporeal membrane oxygenation from the Transfusion and Anemia EXpertise Initiative-Control/Avoidance of Bleeding. DESIGN Systematic review and consensus conference of international, multidisciplinary experts in platelet and plasma transfusion management of critically ill children. SETTING Not applicable. PATIENTS Critically ill neonates and children following cardiopulmonary bypass or supported by extracorporeal membrane oxygenation. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS A panel of nine experts developed evidence-based and, when evidence was insufficient, expert-based statements for plasma and platelet transfusions in critically ill neonates and children following cardiopulmonary bypass or supported by extracorporeal membrane oxygenation. These statements were reviewed and ratified by the 29 Transfusion and Anemia EXpertise Initiative-Control/Avoidance of Bleeding experts. A systematic review was conducted using MEDLINE, EMBASE, and Cochrane Library databases, from inception to December 2020. Consensus was obtained using the Research and Development/University of California, Los Angeles Appropriateness Method. Results were summarized using the Grading of Recommendations Assessment, Development, and Evaluation method. We developed one good practice statement, two recommendations, and three expert consensus statements. CONCLUSIONS Whereas viscoelastic testing and transfusion algorithms may be considered, in general, evidence informing indications for plasma and platelet transfusions in neonatal and pediatric patients undergoing cardiac surgery with cardiopulmonary bypass or those requiring extracorporeal membrane oxygenation support is lacking.

Abstract
Use of viscoelastic tests (VETs), including thromboelastography (TEG) and rotational thromboelastometry (ROTEM), is increasing in the management of anticoagulation in extracorporeal membrane oxygenation (ECMO) patients. A retrospective review of data on 265 pediatric (<20 years old) ECMO patients who underwent VET and were submitted to the Pediatric ECMO Outcomes Registry (PEDECOR) was conducted to describe common coagulopathies in patients who underwent VET; associations between the VET parameters and traditional tests of coagulation; and comparisons in blood product usage in patients who underwent VET with those who did not. We calculated patient-level summary statistics and assessed differences between the groups using χ2 tests (categorical variables) and Kruskal-Wallis and Wilcoxon rank-sum tests (continuous variables). Viscoelastic test was utilized in 77% of patients in the analysis. Platelet dysfunction was the most common abnormality identified by TEG (30.8%) and ROTEM (9.7%). Bleeding patients who had VET performed received more cryoprecipitate transfusions than those who did not have VET (VET median = 9.7 ml/kg; interquartile range (IQR) = 4.3-22.0 ml/kg vs. no VET median = 5.1 ml/kg; IQR = 0-10.4 ml/kg; p = 0.0013). Given the growing use of VET in pediatric ECMO patients, further studies evaluating VET in managing complications as well as aiding in titration of anticoagulation therapy are needed.

Abstract
Purpose: We sought to determine the impact of a comprehensive, context-responsive anticoagulation and transfusion guideline on bleeding and thrombotic complication rates and blood product utilization during extracorporeal membrane oxygenation (ECMO). Design: Single-center, observational pre- and post-implementation cohort study. Setting: Academic pediatric hospital. Patients: Patients in the PICU, CICU, and NICU receiving ECMO support. Interventions: Program-wide implementation of a context-responsive anticoagulation and transfusion guideline. Measurements: Pre-implementation subjects consisted of all patients receiving ECMO between January 1 and December 31, 2012, and underwent retrospective chart review. Post-implementation subjects consisted of all ECMO patients between September 1, 2013, and December 31, 2014, and underwent prospective data collection. Data collection included standard demographic and admission data, ECMO technical specifications, non-ECMO therapies, coagulation parameters, and blood product administration. A novel grading scale was used to define hemorrhagic complications (major, intermediate, and minor) and major thromboembolic complications. Main Results: Seventy-six ECMO patients were identified: 31 during the pre-implementation period and 45 in the post-implementation period. The overall observed mortality was 33% with no difference between groups. Compared to pre-implementation, the post-implementation group experienced fewer major hemorrhagic and major thrombotic complications and less severe hemorrhagic complications and received less RBC transfusion volume per kg. Conclusions: Use of a context-responsive anticoagulation and transfusion guideline was associated with a reduction in hemorrhagic and thrombotic complications and reduced RBC transfusion requirements. Further evaluation of guideline content, compliance, performance, and sustainability is needed.

Abstract
STUDY OBJECTIVE Viscoelastic point-of-care (POC) tests are commonly used to provide prompt diagnosis of coagulopathy and allow targeted treatments in bleeding patients on ECMO. We evaluated the clinical effectiveness of point-of-care (POC) testing for anticoagulation management in patients on extracorporeal membrane oxygenation (ECMO). DESIGN Systematic review and meta-analysis. Eligible studies evaluating the use of thromboelastography- or thromboelastometry-guided algorithms, anti-factor Xa and platelet function testing were selected after screening the literature from July 1975 to January 2020. SETTING Patients on ECMO support. PATIENTS Anticoagulation management on ECMO patients. INTERVENTIONS Rotational thromboelastometry, thromboelastography, alone or combined with platelet function testing. Trials monitoring the anticoagulation effects during ECMO using an anti-factor Xa assay were included in the systematic review. MEASUREMENTS The primary outcomes were bleeding events, surgical revisions, thrombosis events and ECMO circuit change/failure. Secondary outcomes were blood-product transfusions, cerebrovascular accidents, mortality on ECMO, ECMO duration, intensive care unit and hospital discharge rates, and in-hospital mortality. MAIN RESULTS Thirty-one trials enrolling 1684 participants were included in the systematic review. Four trials enrolling 547 subjects were included in the meta-analysis. The use of a POC testing device resulted in improved detection of surgical bleeding (RR: 0.68, 95% CI 0.49 to 0.94, I2 = 0%; χ2 test for heterogeneity, P = 0.02). The use of POC-guided algorithms did not affect bleeding (RR:0.78, 95% CI 0.58 to 1.04, I2 = 47%; χ2 test for heterogeneity, P = 0.09), thrombosis events (RR:1.35, 95% CI 0.86 to 2.12, I2 = 37%; χ2 test for heterogeneity, P = 0.19), or ECMO circuit/change (RR:0.90, 95% CI 0.48 to 1.71, I2 = 28%; χ2 test for heterogeneity, P = 0.75). CONCLUSION Routine use of POC tests did not improve the main clinical outcomes beyond suggesting a diagnosis of surgical bleeding in ECMO patients.

Abstract
Acute fulminant myocarditis (AFM) occurs as an inflammatory response to an initial myocardial insult. Its rapid and deadly progression calls for prompt diagnosis with aggressive treatment measures. The demonstration of its excellent recovery potential has led to increasing use of mechanical circulatory support, especially extracorporeal membrane oxygenation (ECMO). Arrhythmias, organ failure, elevated cardiac biomarkers, and decreased ventricular function at presentation predict requirement for ECMO. In these patients, ECMO should be considered earlier as the clinical course of AFM can be unpredictable and can lead to rapid haemodynamic collapse. Key uncertainties that clinicians face when managing children with AFM such as timing of initiation of ECMO and left ventricular decompression need further investigation.

Abstract
Hemorrhagic and thrombotic complications are a significant source of morbidity and mortality for pediatric patients on extracorporeal membrane oxygenation (ECMO). Optimal anticoagulation therapies and monitoring strategies remain unknown. In 2013, our institution changed the anticoagulation monitoring protocol from activated clotting time (ACT) to antifactor Xa (anti-Xa) levels. We conducted a retrospective review of patients who received anticoagulation management directed by ACT results (n = 96) or anti-Xa levels (n = 72) between January 2010 and March 2016. Hemorrhagic complications occurred in 25% of the ACT group and 39% of the anti-Xa group (p = 0.054). Thrombotic complications were observed in 12.5% of the ACT group and 14% of the anti-Xa group (p = 0.8). There was a greater incidence of extracorporeal cardiopulmonary resuscitations (E-CPR; 36% vs. 15%; p = 0.005) in the anti-Xa group as compared with the ACT group. Secondary analysis showed no difference in transfusion requirements for red blood cells (ml/kg; p = 0.32) or platelets (ml/kg; p = 0.32). There was no difference in average heparin infusion rates (unit/kg/hr) per cannulation (p = 0.17) between the groups. Management of anticoagulation based on anti-Xa levels appears to be as effective as management based on ACT results.

Abstract
INTRODUCTION Extracorporeal membrane oxygenation (ECMO) and Continuous renal replacement therapy (CRRT) are treatments for critically ill patients with respiratory failure and acute kidney injury. However, no reliable factors have been identified to predict survival in patients treated with both ECMO and CRRT. The aim of this study was to identify prognostic factors for discharging intensive care unit (ICU) patients who required CRRT during ECMO. METHODS We retrospectively analyzed data from patients who required CRRT in addition to the ECMO, between April 2015 and March 2018. The patients were divided into two groups: patients who survived and patients who died during ICU hospitalization. We determined their demographic and clinical characteristics, Acute Physiology and Chronic Health Evaluation II (APACHE II) scores, Simplified Acute Physiology Score II (SAPS II) scores, and sequential organ failure assessment (SOFA) scores. Further, we assessed whether these characteristics differed between individuals who did or did not survive the ICU hospitalization. RESULTS We found that the APACHE II and SAPS II scores differed significantly between both ECMO and CRRT treated patients who did or did not survive hospitalization. Further, intracranial hemorrhage during ECMO and CRRT therapy was associated with lower survival rate. CONCLUSIONS Using APACHE II and SAPS II scores might be helpful in making treatment decisions for patients treated with ECMO and CRRT. Intracranial hemorrhage could be a poor prognostic factor. Our findings indicate the potential utility of APACHE II and SAPS II scores to predict mortality in patients treated with both ECMO and CRRT.

Abstract
AbstractWe augmented our standard extracorporeal membrane oxygenation laboratory protocol to include antifactor Xa assays, thromboelastography, and antithrombin measurements. We performed a retrospective chart review to determine outcomes for patients placed on extracorporeal membrane oxygenation (ECMO) prior to and after the initiation of our anticoagulation laboratory protocol. A total of 663 consecutive ECMO runs were evaluated from January 1, 2007 to June 30, 2018. Of these patients, 252 were on ECMO prior to initiation of the anticoagulation laboratory protocol on September 1, 2011, and 411 patients were on ECMO after initiation of the protocol. There were no major changes to our extracorporeal membrane oxygenation circuit or changes to our transfusion threshold during this continuous study period. Transfusion utilization data revealed statistically significant decreases in almost all blood components, and a savings in blood component inflation-adjusted acquisition costs of 31% bringing total blood product cost-savings to $309,905 per year. In addition, there was an increase in survival to hospital discharge from 45 to 56% associated with the initiation of the protocol (p = 0.004). Our data indicate that implementation of a standardized ECMO anticoagulation protocol, which titrates unfractionated heparin infusions based on antifactor Xa assays, is associated with reduced blood product utilization, significant blood product cost savings, and increased patient survival. Future prospective evaluation is needed to establish an antifactor Xa assay-driven ECMO anticoagulation strategy as both clinically superior and cost-effective.

Abstract
Extra Corporeal membrane oxygenation (ECMO) is one of the most advanced forms of life support therapy in the Intensive Care Unit. It relies on the principle where an external artificial circuit carries venous blood from the patient to a gas exchange device (oxygenator) within which blood becomes enriched with oxygen and has carbon dioxide removed. The blood is then returned to the patient via a central vein or an artery. The goal of ECMO is to provide a physiologic milieu for recovery in refractory cardiac/respiratory failure. The technology is not a definitive treatment for a disease, but provides valuable time for the body to recover. In that way it can be compared to a bridge, where patients are initiated on ECMO as a bridge to recovery, bridge to decision making, bridge to transplant or bridge to diagnosis. The use of this modality in children is not backed by a lot of randomized controlled trials, but the use has increased dramatically in our country in last 10 years. This article is not intended to provide an in-depth overview of ECMO, but outlines the basic principles that a pediatric intensive care physician should know in order to manage a kid on ECMO support.

Abstract
OBJECTIVES Patients undergoing extracorporeal membrane oxygenation are at high risk for bleeding and thrombotic complications. Current laboratory methods for assessing the coagulation system may be imprecise and complicate clinical decision-making. We hypothesize that thromboelastography may be more strongly associated with bleeding events than traditional methods and can aid extracorporeal membrane oxygenation coagulation management. DESIGN In a retrospective study, 40 patients with congenital heart disease requiring extracorporeal membrane oxygenation support yielded a total of 159 patient days of data for thromboelastography analysis. SETTING Pediatric cardiac ICU at a single institution. SUBJECTS Pediatric patients (≤ 18 yr) with congenital heart disease requiring extracorporeal membrane oxygenation support. INTERVENTIONS None. METHODS Thromboelastography was performed on whole blood samples collected 6-12 hours following extracorporeal membrane oxygenation initiation and daily for the duration of extracorporeal membrane oxygenation. Bleeding during each 24-hour period was defined as need for re-exploration or need for blood transfusion. Associations between thromboelastography variables and bleeding over each 24-hour period (bleeding vs nonbleeding days) were assessed using mixed effects logistic regression and classification and regression tree analysis. MEASUREMENTS AND MAIN RESULTS Bleeding occurred in 25 patients (63%), contributing 87 bleeding days (55% extracorporeal membrane oxygenation days) for analysis. The probability of bleeding within the 24-hour period was not associated with activated partial thromboplastin time (p = 0.6) or anti-Xa levels (p = 0.3) on that day. The strongest correlate of bleeding was a maximum amplitude less than 55.4 mm on thromboelastography (odds ratio, 3.28; 95% CI, 1.63-6.60; p < 0.001). Bleeding occurred on 73% versus 35% of extracorporeal membrane oxygenation days for maximum amplitude less than 55.4 mm versus greater than or equal to 55.4 mm, respectively. Bleeding occurred on all days when a combination of maximum amplitude less than 55.4 mm and a reaction time greater than 12.9 minutes was present. The lowest risk of bleeding (28% of patient days) was associated with maximum amplitude greater than or equal to 55.4 mm and plasma fibrinogen greater than 345 mg/dL. CONCLUSIONS Thromboelastography-derived variables maximum amplitude and reaction time, along with plasma fibrinogen levels, can help predict bleeding events in children on extracorporeal membrane oxygenation support. Research based on larger patient samples is needed to confirm the specific thresholds identified for bleeding risk stratification for extracorporeal membrane oxygenation anticoagulation management.

Abstract
The study investigated the safety and efficacy of two antithrombin III (ATIII) products in pediatric patients receiving extracorporeal membrane oxygenation (ECMO) by performing a retrospective analysis of patients who received either recombinant ATIII (rATIII) or human-derived ATIII (hATIII). Twenty-two patients were included in the study from January 2014 to September 2015 and all received unfractionated heparin (UFH) as anticoagulation during ECMO. In total, 86 doses of ATIII were included in the analysis in which 37 doses (43%) were rATIII and 49 doses (57%) were hATIII. Unfractionated heparin rates were also evaluated for all cases (n = 86) at 24 hours post-ATIII supplementation. The UFH rate decreased after the administration of both types of ATIII. However, neither the reduction in UFH rate between the two ATIII products (p = 0.52) nor the UFH rates pre- and post-ATIII supplementation at 24 hours (p = 0.08) reached statistical significance. There was a significant difference in cost favoring the rATIII product (p < 0.0001). An ad-hoc estimation of waste associated with ATIII supplementation showed >$100,000 in financial loss of unused drug. Future studies are warranted to evaluate the efficacy of ATIII supplementation in pediatric ECMO.

Abstract
BACKGROUND Extracorporeal membrane oxygenation (ECMO) support in acute respiratory failure may be lifesaving, but bleeding and thromboembolic complications are common. The optimal anticoagulation strategy balancing these factors remains to be determined. This retrospective study compared two institutional anticoagulation management strategies focussing on oxygenator changes and both bleeding and thromboembolic events. METHODS We conducted a retrospective observational cohort study between 04/2015 and 02/2020 in two ECMO referral centres in Germany in patients receiving veno-venous (VV)-ECMO support for acute respiratory failure for > 24 h. One centre routinely applied low-dose heparinization aiming for a partial thromboplastin time (PTT) of 35-40 s and the other routinely used a high-dose therapeutic heparinization strategy aiming for an activated clotting time (ACT) of 140-180 s. We assessed number of and time to ECMO oxygenator changes, 15-day freedom from oxygenator change, major bleeding events, thromboembolic events, 30-day ICU mortality, activated clotting time and partial thromboplastin time and administration of blood products. Primary outcome was the occurrence of oxygenator changes depending on heparinization strategy; main secondary outcomes were the occurrence of severe bleeding events and occurrence of thromboembolic events. The transfusion strategy was more liberal in the low-dose centre. RESULTS Of 375 screened patients receiving VV-ECMO support, 218 were included in the analysis (117 high-dose group; 101 low-dose group). Disease severity measured by SAPS II score was 46 (IQR 36-57) versus 47 (IQR 37-55) and ECMO runtime was 8 (IQR 5-12) versus 11 (IQR 7-17) days (P = 0.003). There were 14 oxygenator changes in the high-dose group versus 48 in the low-dose group. Freedom from oxygenator change at 15 days was 73% versus 55% (adjusted HR 3.34 [95% confidence interval 1.2-9.4]; P = 0.023). Severe bleeding events occurred in 23 (19.7%) versus 14 (13.9%) patients (P = 0.256) and thromboembolic events occurred in 8 (6.8%) versus 19 (19%) patients (P = 0.007). Mortality at 30 days was 33.3% versus 30.7% (P = 0.11). CONCLUSIONS In this retrospective study, ECMO management with high-dose heparinization was associated with lower rates of oxygenator changes and thromboembolic events when compared to a low-dose heparinization strategy. Prospective, randomized trials are needed to determine the optimal anticoagulation strategy in patients receiving ECMO support.

Assessing Anticoagulation in Neonates With Congenital Diaphragmatic Hernia During Extracorporeal Membrane Oxygenation: Does Anti-Factor Xa or Thromboelastometry Provide Additional Benefit? Front Pediatr 2021; 9:685906.

Abstract
Objective: The optimal management of anticoagulation in neonatal/pediatric patients during extracorporeal membrane oxygenation (ECMO) has not been established yet and varies greatly among ECMO centers worldwide. Therefore, we aimed to assess whether the use of anti-factor Xa assay and/or thromboelastometry correlate better than activated clotting time with heparin dose in newborns with congenital diaphragmatic hernia during ECMO. We also examined whether these coagulation assays correlate with thrombotic and/or hemorrhagic complications, when the management of anticoagulation is based only on activated clotting time values. Methods: A prospective observational study in a neonatal ECMO center was conducted. We included all neonates with congenital diaphragmatic hernia born in our institution between March 2018 and January 2019 and requiring support with venoarterial ECMO. A total of 26 ECMO runs were analyzed. During the study, the heparin dose was still adjusted according to activated clotting time values. Measurements of anti-factor Xa assay, activated partial thromboplastin time, and a thromboelastometry from the same blood specimen were performed twice a day. Results: Anti-factor Xa levels showed a moderate correlation with heparin dose, whereas the other tests showed a weak correlation. Four patients (17.4%) had thrombotic complications, 2 patients (8.7%) experienced life-threatening bleeding, and in 11 patients (47.8%) disseminated intravascular coagulation (DIC) occurred. Anti-factor Xa levels were lower in the group with thrombotic complications (0.23 vs. 0.27 IU/ml; p = 0.002), while activated partial thromboplastin time was higher in the group with hemorrhagic complications (69.4 s vs. 59.8 s; p = 0.01). In patients experiencing DIC, heparin dose and anti-factor Xa levels were lower, while no difference in activated clotting time and clotting time in INTEM and INTEM-HEPTEM were shown. Conclusions: Anti-factor Xa levels correlate better to heparin dose than activated clotting time. The use of anti-factor Xa assay instead of activated clotting time for dosing of unfractionated heparin could reduce thrombotic complications in neonates with congenital diaphragmatic hernia on ECMO support. The thromboelastometry showed no additional benefit for this purpose.

Abstract
INTRODUCTION Pediatric cardiac Extracorporeal Membrane Oxygenation (ECMO) is effective, however, bleeding and clotting issues continue to cause significant morbidity and mortality. The objective of this study was to assess the correlation between measures of anticoagulation, the heparin dose in pediatric cardiac ECMO patients as well as to assess covert coagulopathy as measured by thromboelastography (TEG). METHODS Retrospective study of cardiac ECMO patients in a large, academic referral center using anticoagulation data during the ECMO support. RESULTS Five hundred and eighty-four sets of anticoagulation tests and 343 TEG from 100 patients with median age of 26 days were reviewed. ECMO was post-surgical for congenital heart disease in 94% with resuscitation (ECPR) in 38% of the cases. Mean duration of support was 6.3 days. Overall survival to discharge was 35%. There was low but statistically significant correlation between individual anticoagulation measures and low correlation between Anti-Xa levels and heparin dose. There was no correlation between PTT and heparin dose. 343 TEG with Heparinase were reviewed to assess covert coagulopathy which was present in 25% of these. The coagulopathy noted was pro-hemorrhagic in almost all of the cases with high values of reaction time and kinetics and low values for angle and maximum amplitude. CONCLUSION Coagulation monitoring on ECMO may benefit from addition of Heparinase TEG to diagnose covert coagulopathy which can contribute to significant hemorrhagic complications. There is a need for a prospective, thromboelastography guided intervention trial to reduce coagulopathy related morbidity and mortality in ECMO.

Abstract
BACKGROUND Factor consumption is common during ECMO complicating the balance of pro and anticoagulation factors. This study sought to determine whether transfusion of coagulation factors using fresh frozen plasma (FFP) increased ECMO circuit life and decreased blood product transfusion. Secondly, it analyzed the association between FFP transfusion and hemorrhagic and thrombotic complications. STUDY DESIGN AND METHODS Thirty-one pediatric ECMO patients between October 2013 and January 2016 at a quaternary care institution were included. Patients were randomized to FFP every 48 hours or usual care. The primary outcome was ECMO circuit change. Secondary outcomes included blood product transfusion, survival to decannulation, hemorrhagic and thrombotic complications, and ECMO costs. RESULTS Median (interquartile range [IQR]) number of circuit changes was 0 (0, 1). No difference was seen in percent days without a circuit change between intervention and control group, P = .53. Intervention group patients received median platelets of 15.5 mL/kg/d IQR (3.7, 26.8) vs 24.8 mL/kg/d (12.2, 30.8) for the control group (P = .16), and median packed red blood cells (pRBC) of 7.7 mL/kg/d (3.3, 16.3) vs 5.9 mL/kg/d (3.4, 18.7) for the control group, P = .60. FFP transfusions were similar with 10.2 mL/kg/d (5.0, 13.9) in the intervention group vs 8.8 (2.5, 17.7) for the control group, P = .98. CONCLUSION In this pilot randomized study, scheduled FFP did not increase circuit life. There was no difference in blood product transfusion of platelets, pRBCs, and FFP between groups. Further studies are needed to examine the association of scheduled FFP with blood product transfusion.

Abstract
PURPOSE Congenital diaphragmatic hernia (CDH) can cause severe hemodynamic deterioration requiring support with extracorporeal membrane oxygenation (ECMO). ECMO is associated with hemorrhagic and thromboembolic complications. In 2015, we standardized anti-coagulation management on ECMO, incorporating thromboelastography (TEG) as an adjunct to manage hemostasis of CDH patients. The purpose of this study is to evaluate our blood product utilization, choice of blood product use in response to abnormal TEG parameters, and the associated effect on bleeding and thrombotic complications. METHODS We retrospectively reviewed all CDH neonates supported by ECMO between 2008 and 2018. Blood product administration, TEG data, and hemorrhagic and thrombotic complications data were collected. We divided subjects into two groups pre-2015 and post-2015. RESULTS After 2015, platelet transfusion was administered for a low maximum amplitude (MA) more frequently (77% compared to 65%, p = 0.0007). Cryoprecipitate was administered less frequently for a low alpha-angle (28% compared to 41%, p = 0.0016). There was no difference in fresh frozen plasma use over time. After standardizing the use of TEG, we observed a significant reduction in hemothoraces (18% compared to 54%, p = 0.026). CONCLUSION Institutional standardization of anti-coagulation management of CDH neonates on ECMO, including the use of goal-directed TEG monitoring may lead to improved blood product utilization and a decrease in bleeding complications in neonates with CDH supported by ECMO.

Abstract
BACKGROUND During extracorporeal membrane oxygenation, the large contact surface between the blood and the extracorporeal circuit causes a continuous activation of coagulation and inflammation. Unfractionated heparin, a glycosaminoglycan that must bind to antithrombin as a cofactor, is currently the standard anticoagulant adopted during extracorporeal membrane oxygenation. Antithrombin, beyond being a potent natural anticoagulant, acts in the cross-talk between coagulation and inflammatory system through anticoagulation and coagulation-independent effects. OBJECTIVES In this review, we describe, in the adult setting of veno-venous extracorporeal membrane oxygenation, the pathophysiological rationale for antithrombin use, the current practice of administration, and the effects of antithrombin on anticoagulation, bleeding, and outcomes. DATA SOURCES Studies on adults (18 years or older) on veno-venous extracorporeal membrane oxygenation published from 1995 to 2018 in order to evaluate the use of antithrombin. RESULTS In adults on veno-venous extracorporeal membrane oxygenation, antithrombin supplementation has a highly pathophysiological rationale since coagulation factor consumption, systemic inflammatory response syndrome, and endothelial activation are triggered by extracorporeal membrane oxygenation. Eleven articles are focused on the topic but among the authors there is no consensus on the threshold for supplementation (ranging from 70% to 80%) as well as on the dose (rarely standardized) and time of administration (bolus vs continuous infusion). Consistently, antithrombin is considered able to achieve better anticoagulation targets in or not in the presence of heparin resistance. The impact of antithrombin administration on bleeding still shows contrasting results. CONCLUSION Antithrombin use in veno-venous extracorporeal membrane oxygenation should be investigated on the threshold for supplementation, dose, and time of administration.

Abstract
The purpose was to compare time-based vs anti-Xa-based anticoagulation strategies in patients on ECMO. We conducted a systematic review and meta-analysis using multiple electronic databases and included studies from inception to July 19, 2019. The proportion of bleeding, thrombosis, and mortality were evaluated. Twenty-six studies (2,086 patients) were included. Bleeding occurred in 34.2% (95%CI 25.1;43.9) of the patients with anti-Xa-based versus 41.6% (95%CI 24.9;59.4) of the patients with time-based anticoagulation strategies. Thrombosis occurred in 32.6% (95%CI 19.1;47.7) of the patients with anti-Xa-based versus 38.4% (95%CI 22.2;56.1) of the patients with time-based anticoagulation strategies. And mortality rate was 35.4% (95%CI 28.9;42.1) of the patients with anti-Xa-based versus 42.9% (95%CI 36.9;48.9) of the patients with time-based anticoagulation strategies. Among the seven studies providing results from both anticoagulation strategies, significantly fewer bleeding events occurred in the anti-Xa-based anticoagulation strategy (adjusted OR 0.49 (95%CI 0.32;0.74), p < 0.001) and a significantly lower mortality rate (adjusted OR 0.61 (95%CI 0.40;0.95), p = 0.03). There was no significant difference in thrombotic events (adjusted OR 0.91 (95%CI 0.56;1.49), p = 0.71). In these seven observational studies, only a small fraction of the patients were adults, and data were insufficient to analyze the effect of the type of ECMO. In this meta-analysis of observational studies of patients on ECMO, an anti-Xa-based anticoagulation strategy, when compared to a time-based strategy, was associated with fewer bleeding events and mortality rate, without an increase in thrombotic events.

Abstract
INTRODUCTION The frequency of extracorporeal membrane oxygenation in pediatric patients continues to increase, especially in patients with complex congenital heart disease. Providing adequate anticoagulation is necessary for patients on extracorporeal membrane oxygenation and is achieved with adequate heparin administration. Antithrombin is administered to potentiate heparin's effects. However, the efficacy of antithrombin supplementation is unclear and a clear clinical benefit has not been established. We present a large retrospective study examining the effects of antithrombin on pediatric patients receiving extracorporeal membrane oxygenation. METHODS Data for this study were obtained from the Pediatric Health Information System and Pediatric Health Information System+ databases from 2004 to 2015. Pediatric patients receiving extracorporeal membrane oxygenation with a congenital heart disease diagnosis were included and divided into groups that did or did not utilize antithrombin. For all admissions, the following were captured: age of admission, gender, year of admission, length of stay, billed charges, inpatient mortality, the presence of specific congenital malformations of the heart, specific cardiac surgeries, and comorbidities. RESULTS A total of 9,193 admissions were included and 865 (9.4%) utilized antithrombin. Between groups, there were significantly different frequencies of co-morbidities, cardiac lesion types and antithrombin usage over the study period. There were significantly lower odds in the antithrombin group of venous thrombosis. Antithrombin was not significantly associated with hemorrhage; however, antithrombin was associated with increased inpatient mortality and a decrease in length of stay and billed charges. CONCLUSION Antithrombin administration is associated with increased mortality, a shorter length of stay, and decreased billing cost. Recently, antithrombin usage has been decreasing-potentially due to the reported lack of clinical benefit. Together, these results reinforce that antithrombin may not be indicated for all pediatric extracorporeal membrane oxygenation patients.

Abstract
OBJECTIVES To describe the indications and thresholds for plasma and platelet transfusions for pediatric extracorporeal membrane oxygenation, to compare responses to these transfusions and to describe institutional protocols directing their administration. DESIGN Subgroup analysis of two prospective, observational studies paired with survey of sites who enrolled subjects into this cohort. SETTING Fifty-one PICUs in 13 countries. PATIENTS Children (3 d to 16 yr old) were enrolled if they received a plasma or platelet transfusion while on extracorporeal membrane oxygenation during one of the predefined screening weeks. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Forty-eight children on extracorporeal membrane oxygenation received plasma transfusions and 90 received platelet transfusions. Sixty percent of plasma transfusions (29/48) and 79% of the platelet transfusions (71/90) were given for prophylaxis of bleeding. The median (interquartile range) international normalized ratio prior to transfusion, known in 75% of the patients (36/48), was 1.45 (1.20-1.85). The median (interquartile range) total platelet count prior to transfusion, known in all of the patients, was 70 × 10/L (52-90 × 10/L). The international normalized ratio and total platelet count values prior to transfusion did not vary based on bleeding versus nonbleeding indications. The median (interquartile range) reduction in international normalized ratio for mild coagulopathies (international normalized ratio ≤ 2.0) was 0.1 (0.4-0), median (interquartile range) increase in fibrinogen was 0.2 g/L (0.1-0.4 g/L) and median increase in total platelet count was 34 × 10/L (10-74 × 10/L). Through the course of their admission, children supported by extracorporeal membrane oxygenation received a total median (interquartile range) dose of 75 mL/kg (36-159 mL/kg) of plasma transfusions and 92 mL/kg (42-239 mL/kg) of platelet transfusions. Institutional protocols varied but provided guidance for platelet transfusions more commonly. CONCLUSIONS Children supported by extracorporeal membrane oxygenation receive large volumes of plasma and platelet transfusions with some institutional guidance in the form of protocols, but significant variation in practice. Interventional studies are necessary to provide evidence to direct the transfusion of hemostatic products in children supported by extracorporeal membrane oxygenation.

Abstract
Anticoagulation is essential during extracorporeal membrane oxygenation (ECMO) to prevent catastrophic circuit clotting. Several assays exist to monitor unfractionated heparin (UFH), the most commonly used anticoagulant during ECMO, but no single test or combination of tests has consistently been proven to be superior. This retrospective observational study examines the correlation among antifactor Xa level, activated partial thromboplastin time (aPTT), and UFH dose and the association between antifactor Xa level and aPTT with survival and hemorrhagic and thrombotic complications. Sixty-nine consecutive neonatal and pediatric ECMO patients from September 2012 to December 2014 at a single institution were included. Spearman rank correlation was used to compare antifactor Xa level, aPTT, and UFH dose. Significant but poor correlation exists between antifactor Xa level and UFH dose ρ = 0.1 (p < 0.0001) and aPTT and UFH dose ρ = 0.26 (p < 0.0001). Antifactor Xa level and aPTT were weakly correlated to each other ρ = 0.38 (p < 0.0001). In an univariate analysis, there was no difference between survival and antifactor Xa level, aPTT, or UFH dose. Multiple anticoagulation tests may be superior to a single test during ECMO.

Abstract
INTRODUCTION Veno-arterial extracorporeal membrane oxygenation is well-established for pediatric patients with post-cardiotomy heart failure. However, extracorporeal membrane oxygenation support is associated with major complications, that is, hemorrhage and thromboembolism. We seek to report our experience with delayed systemic heparinization during neonatal cardiac extracorporeal membrane oxygenation and its impact on bleeding and thromboembolism. METHODS We retrospectively identified 15 consecutive neonates who were placed on extracorporeal membrane oxygenation after congenital heart surgery during a period of 3 years (2015-2017). Our anticoagulation protocol consisted of full heparin reversal by protamine after switching from cardiopulmonary bypass to extracorporeal membrane oxygenation (target activated clotting time: 120 ± 20 seconds). Administration of systemic heparinization was delayed until postoperative drainage volume declined to <1 mL/kg/h. Primary study endpoints were thromboembolism, bleeding, and requirement of blood products on extracorporeal membrane oxygenation. RESULTS Our cohort (mean age: 13 ± 2.6 days; mean weight: 3.1 ± 0.3 kg; 66.7% male) required post-cardiotomy extracorporeal membrane oxygenation with a mean support time of 4.5 ± 2.2 days. Systemic heparinization was delayed averagely for 18.1 ± 9.3 hours. No thromboembolic events were observed on extracorporeal membrane oxygenation or after weaning. Relevant surgical site bleeding occurred in two patients (13.3%) requiring re-thoracotomy on the first postoperative day. Analysis of transfusion volumes revealed 24.5 ± 21.9 mL/kg/d mean packed red blood cells, 9.6 ± 7.1 mL/kg/d mean fresh frozen plasma, and 7.5 ± 5.7 mL/kg/d mean platelets. In-hospital survival was 86.6% (n = 13). CONCLUSION In this retrospective analysis, the results of delayed systemic heparinization in neonatal post-cardiotomy extracorporeal membrane oxygenation could lead one to conclude that this routine is safe and favorable with low risk for thromboembolic events, reduced postoperative hemorrhage, and reduced blood product utilization.

Abstract
Timely and effective antithrombotic therapy is critical to improving outcome, including survival, in patients with acute coronary syndrome (ACS). Achieving effective platelet inhibition and anticoagulation, with minimal risk, is particularly important in high-risk ACS patients, especially those with cardiogenic shock (CS) or those successfully resuscitated following out-of-hospital cardiac arrest (OHCA), who have a 30-50% risk of death or a recurrent ischaemic event over the subsequent 30 days. There are unique challenges to achieving effective and safe antithrombotic treatment in this cohort of patients that are not encountered in most other ACS patients. This position paper focuses on patients presenting with CS or immediately post-OHCA, of presumed ischaemic aetiology, and examines issues related to thrombosis and bleeding risk. Both the physical and pharmacological impacts of CS, namely impaired drug absorption, metabolism, altered distribution and/or excretion, associated multiorgan failure, co-morbidities and co-administered treatments such as opiates, targeted temperature management, renal replacement therapy and circulatory or left ventricular assist devices, can have major impact on the effectiveness and safety of antithrombotic drugs. Careful attention to the choice of antithrombotic agent(s), route of administration, drug-drug interactions, therapeutic drug monitoring and factors that affect drug efficacy and safety, may reduce the risk of sub- or supra-therapeutic dosing and associated adverse events. This paper provides expert opinion, based on best available evidence, and consensus statements on optimising antithrombotic therapy in these very high-risk patients, in whom minimising the risk of thrombosis and bleeding is critical to improving outcome.

Abstract
OBJECTIVES The aims of this study were to: 1) analyze the cannula-associated deep vein thrombosis frequency after venovenous extracorporeal membrane oxygenation using a CT scan and 2) identify the associated risk factors for cannula-associated deep vein thrombosis. DESIGN Retrospective observational analysis at a single center. SETTING Tertiary referral university teaching hospital. PATIENTS Patients under venovenous extracorporeal membrane oxygenation with a femorofemoral or femorojugular cannulation admitted for acute respiratory distress syndrome or primary graft dysfunction after pulmonary transplantation. CT scan was performed within 4 days after decannulation. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS We included 105 of 228 patients screened. Bacterial pneumonia was the main indication of venovenous extracorporeal membrane oxygenation (46.7%). CT scans were performed at a median of 2 days (1-3 d) after decannulation. Cannula-associated deep vein thrombosis was found in 75 patients (71.4%) despite it having a mean activated partial thromboplastin time ratio of 1.60 ± 0.31. Femorofemoral cannulation induced femoral cannula-associated deep vein thrombosis more frequently than femorojugular cannulation (69.2% vs 63.1%, respectively; p = 0.04). Seventeen of the 105 patients (16.2%) had a pulmonary embolism. Multivariate logistic regression analysis showed that higher the percentage of thrombocytopenia less than 100 G/L during extracorporeal membrane oxygenation period, lower the risk for developing cannula-associated deep vein thrombosis (hazard ratio, 0.98; 95% CI, 0.98-1.00; p = 0.02). CONCLUSIONS Cannula-associated deep vein thrombosis after venovenous extracorporeal membrane oxygenation is a frequent complication. This plead for a systematic vascular axis imaging after venovenous extracorporeal membrane oxygenation. Thrombocytopenia is associated with a reduction in the occurrence of thrombotic events.

Abstract
During extracorporeal membrane oxygenation (ECMO), a delicate balance is required to titrate systemic anticoagulation to prevent thrombotic complications within the circuit and prevent bleeding in the patient. Despite focused efforts to achieve this balance, the frequency of both thrombotic and bleeding events remains high. Anticoagulation is complicated to manage in this population due to the complexities of the hemostatic system that are compounded by age-related developmental hemostatic changes, variable effects of the etiology of critical illness on hemostasis, and blood-circuit interaction. Lack of high-quality data to guide anticoagulation management in ECMO patients results in marked practice variability among centers. One aspect of anticoagulation therapy that is particularly challenging is the use of antithrombin (AT) supplementation for heparin resistance. This is especially controversial in the neonatal and pediatric population due to the baseline higher risk of bleeding in this cohort. The indication for AT supplementation is further compounded by the potential inaccuracy of the diagnosis of heparin resistance based on the standard laboratory parameters used to assess heparin effect. With concerns regarding the adverse impact of bleeding and thrombosis, clinicians and institutions are faced with making difficult, real-time decisions aimed at optimizing anticoagulation in this setting. In this clinically focused review, the authors discuss the complexities of anticoagulation monitoring and therapeutic intervention for patients on ECMO and examine the challenges surrounding AT supplementation given both the historical and current perspectives summarized in the literature on these topics.
